Abstract
The utility model relates to an angle drawing device. The angle drawing device comprises a semi circular angle gauge (1) which is provided with a semi circular gap of which the circle center is the circle center of a dial; the angle drawing device is also provided with a straight ruler (2) which is connected to the circle center of the dial through a hinge shaft; and the hinge shaft is close to one side of one long side of the straight ruler (2). The problem that the angle drawing steps are complex at present is solved.
Description
Technical field
The utility model relates to a kind of angle drawing device.
Background technology
People often can run into the situation at the angle that need to draw some special angles in study, teaching and work.Drawing now the angle generally all needs to use protractor and ruler, and step is more loaded down with trivial details.
The utility model content
Technical problem to be solved in the utility model is that a kind of angle drawing device is provided.Use this angle drawing device can draw easily the angle of special angle, to solve the problem of present picture angle complex steps.
In order to solve this technical problem, the utility model by the following technical solutions:
A kind of angle drawing device is characterized in that: comprise a semicircle protractor, described protractor is with a semicircle vacancy take the dial center of circle as the center of circle; Also with a ruler, described ruler is connected to the dial circle centre position by jointed shaft to described angle drawing device; Described jointed shaft is near one of them long limit one side of described ruler.
Good effect of the present utility model is:
When using the utility model angle drawing device, can rotate first ruler, so that the angle of required angle can directly be drawn out in the long checkpost of the close rotating shaft of ruler then on the specific angle of protractor dial.Solved the problem of present picture angle complex steps.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of angle drawing device comprises a semicircle protractor 1, and described protractor 1 is with a semicircle vacancy take the dial center of circle as the center of circle; Described angle drawing device is also with a ruler 2, and described ruler 2 is connected to the dial circle centre position by jointed shaft.Described jointed shaft is near one of them long limit one side of described ruler 2.
When using the utility model angle drawing device, can rotate first ruler 2, so that the angle of required angle can directly be drawn out in the long checkpost of ruler 2 close rotating shafts then on the specific angle of protractor 1 dial.Solved the problem of present picture angle complex steps.
